there is a very noticeable difference between diesel and lpg v8 and 3.9 on arent the most robust engine

My 3.9 returns 16mpg on petrol and 26 and a bit on gas?
The average diesel is what? 25 - 32 dependant on how lead footed the driver is?
With diesel coming in at a little more expensive than petrol per gallon the difference in cost to cover 100 miles will be negligible.

If you engage a diesel driver in conversation the first thing they will tell you about their vehicle is “how cheap to run it is” never how nice the ride is or how plush the interior etc…
I would argue that the relatively minor cost difference at the pump is worthy of the refinement and available power for having a V8 under the bonnet. Certainly it’s far more relaxing traveling in relative silence rather than having to endure the row and racket produced by an equivalent diesel model.

In truth, had our discovery not come with LPG fitted to it, I wouldn’t have bothered installing the system as fuel consumption has never once been on my list of priorities when choosing a vehicle. I appreciate that is not necessarily the case for everyone, however. I suppose it boils down to what you as an individual can justify or are prepared to put up with?

you mean it returns the cost of 26mpg on gas ?
 
In my opinion i wouldnt touch a petrol no matter how much power it had. My 300tdi does the job perfectly and it will quite happily sit at 75-80 on the motorway which is plenty for me.I also run mine on cooking oil and have done for the last 2 years and at 90p per litre i think it makes it quite a bit more economical than any lpg v8. As for noise all i do is turn up the stereo one more notch than what you would have to do in a v8 and so this is not a problem.Different people have different opinions as to whether they go petrol or diesel but at the end of the day it all depends on what you want.

I think he should get one and fit power steering to make it more liveable if he isn't man enough to use it without :rolleyes:

If not you could always buy a gaylander……or a jeep :eek:

unless you have a disability of some form then there is no reason to ever fit powered steering to a Series... If you can't cope you're clearly not the right person for a Series :)

I think I might be fitting it for the midget but in her defence she is tiny :eek: although I've told her its not that bad to drive without it

Once mines up and running (next weekend fingers crossed as I have wammers walkthrough) I'll let her drive it to see

Have you actually driven a D2 TD5 :confused:

I think possibly not :(

My D2 TD5 is quiet, responsive and has more power than I would ever need and I do not have to endure the 'row and racket' that you describe.

Mind you anything's an improvement on an MGB, my dad used to restore the damn things, it was my job to dispose of them when he retired :mad:
 
I used to have a 3.9 on gas, but the range on gas was only about 170 miles, so driving 4 miles out of my way to get to a gas station was noticeable! Plus you need to warm it up on petrol so the mpg comparison isn't an exact science.

I much prefer my current 300. It's not that noisy and I actually prefer how it drives off road. I can go wading without worrying about electrics and I don't need to worry about hitting the underslung gas tanks (been there, done that - expensive outcome!).

Yeah i would /do worry about underslung tanks , my range is about 350 on LPG big tanks and lots of em , i think next time round will be going for a d2 or maybe even a d3 TDI depending on money and the times but do love my v8 :D

ive had both 3.9 lpg and td5 ,even on lpg it was noticeably dearer on fuel plus there arent that many places to get lpg ,you spend most of your time looking for gas on long journeys ,and td5 certainly goes as well as v8 ,i like a v8 but there just not really practical
 
i think a TD5 sounds pretty good aswell! not as good as a v8 but very nice any hows, did want a td5 but price difference and i didnt have enough ££ at time (nor now)
 
Yeah i to wanted a v8 on gas but after speaking to people about them i went and got a 300tdi. its modded jacked and running 33" muds. I'm still getting around 26mpg. yes a v8 has more get go, but the tdi well looked after can be a very good engine. hardly notice the sound from mine, could be the mud tyres and light bar causing that thou lol.

I have.... still would rather have a 300tdi every time :D
 
For me I think I'll stick to derv. Stick to what I know I suppose, and with regards, to power steering in a series... although a series isn't really practical for me, I think power steering or a tdi is sacramental! Each to their own, but I think series are best left untouched, save for maybe a horseshoe, and a towrope on the bumper lol. I certainly didn't need power steering on mine, it was just the slowness, the noise, and the clutch judder that drove me nuts lol. It was lovely on the greenlanes, and down the country lanes.

I'm looking forward to being back behind the wheel of Landy, and especially the nice high up position.

Got my eyes peeled for a nice smart tdi (with beige interior, 'cos I'm picky), or a cheap and cheerful 90. The search goes on.

My other halfs parents have a D2 TD5. I'm sure it's very nice if you like that sort of thing but we don't do diesel in this household.
A couple of years back when Nicola had a Triumph Stag we were V8 only household come to think of it. :D

Well, at the risk of labouring the point, that's down to what you can justify isn't it? When there's only a few MPG in it, I don't see that it really matters?
You have to sit down and actually work out what your personal situation is as to whether it'd be viable or not.

My priority has always been "smiles per mile" as opposed to "miles per gallon" so it's not somethign I keep tabs on particularly.
In our situation I cannot forsee there being a fuel supply issue - I can think of 7 places reasonably locally that sell LPG. plus another in Derby itself if we have to go that far. Every other car you see in Derbyshire is a Landrover so that may go some way to explaining why it's so freely avaliable around here? Although, granted we are not as fortunate as others.
The only long journey we will ever do in our Discovery will be restricted to the annual 200 mile round trip at Christmas to see all the family since any other long journeys i.e holidays we go touring in both of the sports cars which run on normal super unleaded.
So on that basis, a V8 is perfectly practical for our situation although we'd have still bought the thing even if there were no LPG system as power and refinement are the bigger priority to us rather than running costs.

In any case... Good luck to the OP for whatever you go for. I'm certainly finding our discovery to be a very comfortable and capable winter daily.
 
don't the v8's have a problem of cracking in the bores. remeber something about that , that was another reason why i didn't buy one.
